../srp_daemon/srp_daemon.c: In function 'get_shared_pkeys':
../srp_daemon/srp_daemon.c:1080:50: warning: '__builtin___snprintf_chk' output may be truncated before the last format character [-Wformat-truncation=]
snprintf(pkey_file, sizeof(pkey_file), "pkeys/%d", pkey_index);
The given format string requires 18 bytes to handle all expansions of %d
